Ital: qctober 2 1 1 This invention relates 'toa device for collectingmechanical parts-'suchasscrews, Eboits, rivets and the like manufacturedon automatic machines and for transferring them conveniently directed'alignment to successive operations.

With the device according to this invention,

collecting, directing and transport of the parts take placeautomatically. device is provided direction are returned to therevolving drum forbeing recycled.

Further features o the device will appea f the following specificationin which reference is made to the annexed drawings which show by way ofexample a construction thereof.

Fig. 1' is a section of theldevice on a vertical P ane extendin throu hits axis.

F g, :2 is a side elevation .ofth device;

- F g.- 3 is a plan view partly in section of the device showing therollers forming the conveyor.

Fig.4-is'a diagrammatic .end view of the'rollers.

With reference to the drawings, l denotes the frame on which a drum 2with horizontal axis is rotatably mounted. The drum 2 is formed by ahollow casing having a cylindrical section 3 merging into the largerbase of the next section 4, which is frustrum-shaped. The drum issupported by means of two end rings 5 and 6.

The ring 6 is freely rotatable on the supporting hub 1 formed on thefront side of the frame and the ring 6 rotated on the supporting hub 8formed on the rear side of the frame.

Radial plates 9 are formed inside of the cylinder section 3 of the drum2 and integral with the drum walls over a length substantially'equal tothe length of the cylindrical section. A groove pulley I is formed onthe outer surface of the said cylindrical section and is driven by meansof a belt by a further pulley keyed on a drive shaft carried by supportsII on the brackets l I' encased integrally with the frame I.

The opening l2 of the hopper is provided at the hub I at the front ofthe frame and communicates with the inside of the drum 2. Its lowersurface I3 is in the form of a gradient to draw 2 Glaims. (C1 lit-r165).

articles introduced through the opening and cause them to slide withinthe drum,

The huh. I is provided on top. with inclined plane I4 reaching withinthe drum 2 to, enable articles falling on the said plane to slide bygravity towards the inside of the drum.

The opening 15 for communication with the inside of the drum 2 bored onthe rear-side of the frame I is at the hub 58. The lowersurface of thisopening forms an inclined surface to cause ticles falling on saidsurface to slide within the drum.

Two rollers l6 and I6. haying parallel axes er.- ranged on the sameplane inclined at its front end towards the back of the machine are ar:ranged lengthwise within the drum 2 above its axis, and are suitablysupported by the fra e The axes of said rollers are placed apart inorder to lea e between their opposite internal surfaees a r determined cearance in cee an e with the nature andsize of he pa ts uppl ed thedevice.

On rotation of the drum the blades 9 convey the partssupplied as above upwardly and place them on the gradient [4 by whichthey are guided on to the surface of the rollers l6 and I6. Theserollers perform an opposed rotary motion in the direction shown in Fig.3 and convey the parts placed thereon by virtue of their inclination andof the said rotary motion towards the outlet of the drum 2 and directthem on their travel with their shank S turned downwards and their headH supported by the rollers as shown in Fig. 3.

A roller I1 is conveniently supported on the frame I and rotates on asuitable pivot, its outer surface being situated between rollers l6 andIt at a predetermined distance from the top surface of the rollers, andperforms a rotational movement in the direction indicated on the drawinggradient 15 which returns them to the. drum 2 from which they arerecycled as described above..

The device may be varied with respect to the drum, and to cause them tofall on the lower, j

details described and shown in the drawing by way of example withoutdeparting from the,

scope of this invention.

What I claim is:

1. In a machine for feeding headed blanks,

the combination of a support, a holder supported by said support andopen at the rear end thereof, said holder being adapted to contain aquantity of blanks, means for rotating said holder, said holder beingformed by a frusto-conical rotatable body having fixed to its larger enda cylindrical body, means for feeding the blanks to said holder to thecylindricalend, radial plates fixed to the inner wall of the cylindricalbody and bringing on rotation of the holder the blanks to their-topposition in the holder, an inclined plane fixed to the support of theholder, said inclined plane receiving the blanks falling'from the top ofthe holder, a pair of rollers having substantially parallel downwardlydirected longitudinal axes, the opposed surfaces of said rollers beingspaced apart by a distance such that a headedblank may be supportedtherebetween by engagement of the enlarged portion, while the part ofthe headed blank of-smaller cross section is directed downwardly betweensaid rollers, said rollers being placed below the previously mentionedinclined plane, means for rotating 'said rollers so that the opposedsurfaces of the rollers rotate in an upward direction, and means fordischarging from said rollers any blanks not arranged in the desiredmanner near the end of the holder of smaller cross section, the holderbeing so placed that, on rotation thereof, the blanks placed on thebottom of the holder are fed to the cylindrical end of said holder.

2. In a machine for feeding headed blanks, the combination of a support,a holder supported by said support and open-at the rear end thereof,

4 said holder being adapted to contain a quantity of blanks, means forrotating said holder, said holder being formed by a frusto-conicalrotatable body having fixed toits larger end a cylindrical body, meansfor feeding the blanks'to said holder to thei cylindrical end, radialplates fixed to the inner wall of the cylindrical body and bringing onrotation of the holder, the blanks to their top position in the holder,an inclined plane fixed to the support of the holder, said inclinedplane receiving the blanks falling from the top of the holder, a pair ofrollers having substantially "parallel downwardly directed longitudinalaxes,

the'opposed surfaces of said rollers being spaced apart by a distancesuch that a headed blank may be supported therebetween by engagement ofthe enlarged portion, while the part of the headed blank of smallercross section is directed downwardly between said rollers, said rollersbeing placed below the previously mentioned inclined plane, meansforrotating said rollers so that the opposed surfaces of said rollersrotate in an upward direction, a roller supported on the machine frameandso arranged that its outer surface is situated between the.twocounterrotating rollers at a predetermined distance from the top surfaceof said rollers, and means'for rotating said last mentioned roller sothat the surface of the roller facing the two previously mentionedcounter-rotating rollers is displaced towards the raised ends of saidcounter-rotating rollers, said last mentioned .roller causing the blanksplaced on the counter-rotating rollers in incorrect position to fallinto the holdenthe holder being so placed that, on rotation thereof, theblanks placed on the bottom of the holder are fed to the cylindrical endof said holder.
